"BUILDING-TILE mosses.

Z '0 all whom it may concern:

Be it known that I, ROBERT E. HUNN, a citizen of the United Oakland, in the county of Alameda State of California, have invented new useful Improvements in Building Files l/Valls Thereof, of whiclrthe following specification.

This invention relates to building tiles and walls thereof; and has for its object to provide a simple and easily manufactured tile of terra-cotta of which a number can .easily be assembled to form a wall of improved strength and rigidity haying perfect ventilation and increased protection against the passage of moisture therethrough. This object is accomplished by the provision of interlocking hollow tiles that can be easily and quickly laid up in double thicknesses to form a Wall having continuously extending Vertical fines, and in which the interlocking members on the individual tiles cooperate in various positions to permit staggering of the same, whereby toovercomc the presence oftransverse interstices through the wall, and means whereby the cooperating tiles may be wedged and cementedpermanently in interlocked position.

In the accompanying drawing, Figure 1 is a broken perspective view of a corner of and and a nd is a a Wall formed of my improved tiles; Fig. 2-

is an enlarged plan View of the tile.

Referring to the drawing, 1 indicates my improved hollow buildinf tile. It has straight ends 2 and an outer side or face 3, the outer surface of which may be either corrugated when the tile forms the inner side of the wall, or ornamental when it forms its outer side. Its inner side or face is formed with four tongues 6 all extending from said face in the same oblique direc--' 'tion and spaced from each other 1n such a.

manner that the tongues of an adjacent inner or outer tile will fit into the recesses between the tongues of an outer or inner tile. Said tongues have a long sloping -surface 7 and a short sloping surface 8 and a rounded end 9 between said surfaces. The short sloping surfaces 8 of the tongues of against each other. and the rounded end 9 of one tile exactly fits into the cavity between the short surface 8 and long surface 7 of an adjacent tile. The long surfaces 7 of adjacent tiles do not exactly fit against each other, but leave an intervening space to I'BCelVG .mortar- 11,

which, when hardened. forms a lreyhetweeu said tiles, }n'eventing them fIOlll being moved longitudinally with reference to each other. For better holding the tiles together each sloping surface 3 formed. a little beyond the center with a projection12 -said projections 12 of the adjacent tongues of twoadjacent tiles additionally serving, in conjunction with the mortar therehetwcen; to hold in position the adjacent tiles. llach tile is-forn'ied with three oblique transverse walls 1%? GXtQl'KllllQ from the outer straight face of the tile to the three parts of the inner face in which are'contained the recesses between the tongues. These three transverse walls form with the ends of the tile four cavities. y

The tiles are so constructed that. when assembled to form a walh the end of each inner tile is opposite, not to the middle of the adjacent outer tile. as has been customary to this class of devices, but to the second one of the four tongues of said adjacent outer tile. Consequently if the outer tiles are placed vertically in staggered relation with each other, so that each outer tile comes exactly above the middle of the outer tile immediately below it, the end. of the adjacent inner tile is not in the same vertical plane as the end of said outer tile immedh ately below, but is to one side thereof, and is horizontally separated therefrom by one of the mortar-filled spaces between the lone surfaces 7. This" arrangement prevents any moisture seeping in betweenv the outer tiles through the interstices between'the inner tiles and it is of especial importance because it permits of assembling the inner and. outer tiles also in staggered relation to each other vertically F or this purpose. there are pro vided at the bottom of the inner wall special tiles 13 of only half the height of the other tiles. The lowermost row of outer tiles extending; by half its height above the lowerposite to the uncture between the next two lower inner tiles, and consequently there would be a chance for moisture to seep containing through the wall. By so forming the tile that its end must be exactly opposite to the part of a horizontally adjacent tile which is at a distance of about one-third from the end of the latter, the above seepage is avoided, and at the same time the advantage is obtained that the tiles can be assembled in staggered relation vertically.

It will he observed by reference to Fig. 1 that the oblique transverse walls of the in ner and outer tiles are in line with each other and that in all cases the juncture between two adjacent inner tiles and also be tween two adjacent outer tiles is immediately over one of said transverse walls.

This is an additional prew'entuin against leakage through the-wall between the tiles.

Two special forms of tiles are required to form a corner of a wall, the tile 15 for the outside of said corner being only about three-fourths of the length of an ordinary tile. and the tile 16 at the inside ot-the corner being: somewhat reduced in length from the ordinary tile.

The cavities formed by the transverse walls 10 enable vertical tie rods to extend where desired from floor to floor thus tying the entire wall to the building, each cavity a tie rod being tilled with. concrete around the tie rod. By forming the transverse members 10 obliquely, with respect to the side walls, and positioning themwith regard to the overlying tiles, tie webs are provided which otter supporting means oi increased area for the abutting ends of said overlying tiles, as will be seen by'reteronce to Fig. 2 where the tie webs extend diagonally of the rightangular end walls of the abutting and overlying tiles.

- I claim '1. A building tile having; a plurality of obliquely extending tongues projecting from its vertical side face to cooperate with and overlap similar tongues on the adjacent face of an oppositely disposed tile, the opposite and i'ion-ad omingtongues. forming between their tongues being them at their elongated sides cavities for the reception of binding material.

2. A building tile having on its vertical side face a plurality of obliquely extending tongues inclined adapted to cooperate with and overlap similar tongues on the adjacent side face of an oppositely disposed tile, and provided with double concaved surfaces on the elongated in the same direction and sides of the tongue to form cavitiesfor the reception of binding material, whereby to provide an interlocking connection between opposite tiles.

3.'A building tile having a series of obliquely extending tongues carried on its vertical side iace adapted to cooperate with and overlap similar tongues on an oppositely disposed tile, said tongues provided on their elongated sides with double concaved surfaces forming a ridge where they meet, whereby to provide cavities between the cooperating tonguesfor the reception of binding materiahthe adjacent ridges cooperating to prevent relative endwise movement 0 opposite tiles.

4. A wall comprising building tiles having interlocking vertical faces, said faces comprising obliquely extending tongues upon the tiles at'one side of the Wall inclined in the same direction and obliquely extending tongues on the tiles at the other side of the wall inclined in a direction oppo site to the first mentioned tongues and overlapping therewith, said tiles intermediate 'concaved'faces to form cavities for the reception of mortar, and cooperating shoulders whereby to lock said tiles in place against endw'ise movement.
